Layer ham and swiss cheese in a casserole dish and get a meal so delicious your husband will be begging for more! It tastes like a warm sandwich in a bowl.

A Cozy Ham and Swiss Casserole That Fits Real Life

Some evenings call for comfort food, but time is short and energy is even shorter. You might want something warm and satisfying that feels homemade without requiring hours in the kitchen. That is where a layered ham and Swiss casserole can make dinner easier.

This dish brings together familiar flavors — tender chicken, savory ham, and melted Swiss cheese — in a simple baked meal. Many people enjoy classic chicken cordon bleu, but the traditional version takes time to assemble and cook. A casserole version offers a practical alternative that still delivers the same comforting taste.

Instead of stuffing and breading individual portions, everything cooks together in one dish. The result is a creamy, hearty meal that works well for busy weeknights or relaxed weekend dinners. It is also a useful recipe when you need something dependable that reheats well the next day.

Why Simple Casseroles Still Matter

Meals like this remain popular because they solve a common problem: how to feed a family with minimal effort and cleanup.

One-dish casseroles allow you to combine protein, dairy, and seasonings in a single pan. This can save time in both preparation and washing up afterward. For many households, that convenience makes a real difference on busy evenings.

Another advantage is flexibility. Ingredients such as cooked chicken or leftover ham can easily be used, helping reduce food waste while keeping grocery costs reasonable.

This type of recipe also stores well. Leftovers can be packed for lunches or reheated for another dinner, which helps stretch one cooking session into multiple meals.

How the Layers Work Together

The structure of this casserole helps create balanced flavor in every bite.

The chicken forms the base and provides the main source of protein. Using cooked chicken, such as rotisserie chicken, keeps preparation simple while still providing good texture.

The ham adds a slightly salty, savory flavor that complements the mild taste of the chicken. When baked together, the flavors blend into a familiar sandwich-like combination.

Swiss cheese melts smoothly and contributes a mild, slightly nutty taste. It helps bind the layers together and gives the casserole its creamy character.

The sauce brings moisture and richness. A mixture of milk, broth, sour cream, and seasoning helps keep the chicken tender while supporting the overall flavor.

The breadcrumb topping adds contrast. While the interior stays soft and creamy, the top becomes lightly crisp and golden during baking.

Ingredients for a Reliable Weeknight Meal

Servings: 6

Main Ingredients

• 3 cups cooked chicken, shredded or cubed
• 8 ounces sliced ham, cut into strips or squares
• 8 ounces Swiss cheese, sliced or shredded

Sauce

• 2 cups milk
• 1 cup low-sodium chicken broth
• 1 cup sour cream or plain Greek yogurt
• 1 can condensed cream of chicken soup
• 1 teaspoon Dijon mustard
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/2 teaspoon dried thyme (optional)
• 1/2 teaspoon salt
• 1/2 teaspoon black pepper

Topping

• 1 1/2 cups breadcrumbs
• 4 tablespoons melted butter
• 1/2 cup grated Parmesan cheese

Basic Preparation Steps

Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

Spread the cooked chicken evenly in the bottom of the dish.

Layer the ham over the chicken, followed by the Swiss cheese.

In a bowl, whisk together the milk, broth, sour cream, soup, mustard, and seasonings until smooth.

Pour the sauce evenly over the layers.

Mix breadcrumbs, melted butter, and Parmesan cheese, then sprinkle the mixture on top.

Cover loosely with foil and bake for 20 minutes.

Remove the foil and bake another 15–20 minutes until bubbling and lightly browned.

Let the casserole rest for about 5–10 minutes before serving.

This short resting period helps the sauce settle and makes serving easier.
